Solar Frontier Breaks CZTS Cell Efficiency Record2013-12-10

Solar Frontier Breaks CZTS Cell Efficiency Record
World-record 12.6% cell efficiency achieved with IBM and TOK
 
TokyoDecember 10, 2012 Solar Frontier announced today that it has set a new conversion efficiency record for CZTS solar cells (0.42cm²) at 12.6%. The latest world record was achieved in joint research with IBM (NYSE:IBM)  and Tokyo Ohka Kogyo (TOK), and has been independently verified by Newport Corporation[1]. The details have been  published in the Advanced Energy Material, journal on Nov 27[2]
 
CZTS stands for key ingredients copper, zinc, tin, sulphur and selenium. Inexpensive and with abundant supply, these materials offer CZTS a cost-competitive advantage over other photovoltaic technologies. The new 12.6% world record eclipses the previous record of 11.1%, which was also set by Solar Frontier and its joint-research partners.
 
 “Breaking our previous record at such a fast pace shows the potential of CZTS for mass production in the future, and we are now in a position to drive that efficiency even higher,” said Satoru Kuriyagawa, Chief Technology Officer of Solar Frontier.
 
Solar Frontier is the world’s largest provider of CIS thin-film photovoltaic solutions. Its Atsugi Research Center in Kanagawa, Japan, has also achieved standing world record conversion efficiencies of 17.8% on a 30cm by 30cm CIS submodule and 19.7% for non-cadmium CIS cell. Solar Frontier’s CIS modules, manufactured in Japan, are offered in commercial volumes at up to 13.8% efficiency, the highest of any mass produced thin-film modules.
